Description

Verfahren zur Ausnutzung der Abwärme vtin Gasen oder Dämpfen aus Verbrennungsöfen oder anderen Vorrichtungen. Die aus Vertriennungsöfen oder anderen Vorrichtungen kommenden heißen Gase oder Dämpfe werden, wo erforderlich, in der Regel in berieselten Kühlröhren, durch welche die Gase geleitet werden, mit .Hilfe von Wasser gekühlt. Der größte Teil der vom Wasser aufgenommenen Wärme geht hierbei verloren.Process for utilizing waste heat from gases or vapors from incinerators or other devices. Those from distribution ovens or other devices Incoming hot gases or vapors are usually sprinkled in where necessary Cooling tubes through which the gases are passed, cooled with the aid of water. Most of the heat absorbed by the water is lost.

Die Erfimdung betrifft ein Verfahren zur Ausnutzung der Albwärme von Gasen oder Dämpfen in Zellstoffabriken. Gemäß - tdem neuen Verfahren werden die heißen Gase nicht mit Wasser, sondern mit frischer Sulfitlauge gekühlt, so daß die Abwärme den Zellstoffkochungen zugute kommt. Das neue Verfahren besteht darin, daß die Kühler für die Gase.: oder Dämpfe (z. B. für die der Schwefelkiesofen.gase), von Frischlauge bespült werden, welche in gesehlossenem System'j unter Druck durch die Kühlvorrichtungen hindurchgeleitet wird. Ein Verlust an , schwefliger Säure wird auf diese Weise vermieden.The invention relates to a method for utilizing the Albwärme of Gases or vapors in pulp mills. According to the new procedure, the hot gases are not cooled with water but with fresh sulphite liquor so that the Waste heat benefits the pulp boilers. The new method is that the cooler for the gases .: or vapors (e.g. for those of the pebble-sulphurous furnace gases), be rinsed by fresh liquor, which in a closed System'j under pressure the cooling devices is passed through. Loss of sulphurous acid is avoided this way.

Die so erwärmte Lauge kann unmittelbar dem Kochprozeß zugeführt werden, indem sie z. B. unmittelbar in den .mit Holz beschickten Kocher eingeführt wird, oder sie kann zunächst in einem besonderen Behälter noch weiter durch Abgase usw. vorgewärmt werden.The lye heated in this way can be fed directly into the cooking process, by z. B. is introduced directly into the stove loaded with wood, or it can first be filled with exhaust gases etc. in a special container. be preheated.
